Abstract
Rock collapses phenomena are one of the main processes constituting the geological hazard. Most commonly, the concept of "collapses" covers several different types of rock deformations: rockfall (linear and wedge-shaped), rock toppling, etc. It is difficult to predict the exact moment of the occurrence of a rock collapse. For this reason, it is necessary to know the potentially dangerous regions and areas in which this phenomenon may occur or to plot the sites by susceptibility to rock collapses. This will give an idea of location of hazardous areas with preconditions for collapses, and on this basis the necessary preventive measures can be identified. The main types of rock collapses and slope conditions - engineering geological, geomorphological, tectonic, are discussed. The methodological approach is given for the mapping of the terrains by susceptibility to rock collapses. Issues related to the scale of the maps compiled are clarified.
